The Northwest Visa Signature offers 25,000 miles after $500 in purchases (the Platinum card offers 20,500).
The annual fee is hefty — $90.00 for the Visa Signature or $55 for the Visa Platinum.
But the miles are easy and it’s nearly your last shot before Northwest Worldperks folds into Delta Skymiles. It’s a 25,000 mile opportunity you won’t have again, a bonus opportunity in addition to the Delta co-branded Amex offerings.
